Is there a way to hide posts that have identical titles on identical sibling communities? My feed gets cluttered really fast when I’m subbed to a big community on two different instances because people often crosspost. I’m tempted to leave one, but I don’t want to miss anything.
No, not with out a rethink of Lemmy writ large or without some changes to the activity hub protocol, you are correct to suggest that a ‘glued on’ cross posting solution might be the best answer. It also might be worth considering that Lemmy may well be the v1.0 and this issue could be addressed in a future protocol.
I’ll keep thinking on it, because its really the downfall of the whole thing. Lemmy can’t be a reddit killer because of this very issue. It forces a splintering of the network. Some how, users and posts need the ability to ‘move around’ the fediverse.
